MISSOURI SPEED BOAT AND BOAT HULL Original No. 1,631,400, dated .Tune 7,1927, Serial No. 37,672, filed June 17, 1925. Application for reissueled November 7, 1929. Serial'No. 405,499.

This invention relates to speed boats and the primary object of theinvention is to provide a boat which may be capable of4 being propelledover marshy waters where the waters contain considerable long grass andweeds. In certain parts of the country, particularly in the South, thereare wide eX- panses of water where boats with deep draft cannot navigateso he provided a flat bottom boat with means for providing a cushion ofair between the water and the bottom of the boat so that the boat whenin action will be buoyed slightly above the waters surface.

The novel construction of the invention will be apparent by reference tothe following description in connection with the yaccompanying drawings,in which Fig. 1 is a perspective view of the boat constructed inaccordance with this invention, and

Fig. 2 is an end View of the same.

The boat is shown as having a flat bottom 1 with an upturned bow 2. Theboat may be provided with a coping 3 and a prepeller 4 driven by anappropriate mechanism may supply the necessary power. Near th respectiveedges 5 and 6 of the boat are two depending fins 7 and 8, runninglongitudinally of and sup orted by the bottom of the boat. The insl??and 8 are deep enough to provide an air pocket 9 which, when the boatattains sufficient speed, will cause the air to pack under the bottom 1so as to have sulicient buoyancy to raise the boat above the surface ofthe water. Therefore, the boat when in action will be in the form of ahydroplane.

It is vfound that by providing the longitudinally depending ins so as toprovide the air pocket; the boat can attain considerable speed, as muchas fifty miles an hour, over marshy streams and water courseswhereordinarily it would be diiicult to propel a boat at all.

What is claimed and desired to be secured by Letters Patent is:

1. A boat having a smooth, Hat, uninterruptd bottom, an inclinedsubstantially plane faced bow merging therewith, and a pair ofsubstantially parallel fins extending longitudinally of said bottomadjacent the side edges thereof and depending therefrom substantiallyperpendicular to said botom, said fins having bevelled forward ends, theedges of which lie in the plane of the inclined faced bow.

2. A boat having a smooth, flat, uninterrupted bottom, an inclinedysubstantially plane faced bow merging therewith, and a pair ofsubstantially parallel fins extending longitudinally of said bottomadjacent the side edges thereof and depending therefrom substantiallyperpendicular to said bottom, said fins having bevelled forward endsac.- jacent the junction of said bow and bottom, the edges of which liein the plane of the inclined faced bow.

In testimony whereof I herewith this 1st day of November, 1929, afliX mysignature, at Kansas City, Missouri.
